Description
The Earthworks SR314 High Definition Handheld Vocal Microphone
utilizes a pre-polarized condenser element coupled to a dedicated
wideband transformerless preamplifier that requires standard 24-
48V Phantom Power. The SR314 features an exceptionally flat 20Hz
to 30kHz frequency response, fast impulse response, low handling
noise, a uniform cardioid polar pattern and high SPL handling ca-
pabilities. It provides excellent uncolored rejection of sounds arriv-
ing off-axis and yields more gain before feedback than conventional
vocal microphones. A mic clip for stand mounting and a protective
fabric bag are included with the microphone.
In Use
Using a standard XLR-3 cable, connect the SR314 to a microphone
preamplifier capable of supplying 24-48V phantom power @ 10mA.
It is normal for any phantom powered mic to “pop” when powered
up, so be sure to mute the speakers or headphones when phantom
power is first applied. Allow up to one minute for the microphone to
settle before un-muting.
Care of Microphone
The Earthworks SR314 is a precision instrument crafted to provide
years of top performance and reliability. Following these simple
guidelines will help to protect your investment in the SR314:
• The stainless screen can be removed if it requires
cleaning.
a. First unscrew the top half of the microphone
(i.e. the basket).
b. Unscrew the top stainless screen assembly,
then remove the thin stainless steel pop filter.
c. Clean both sides of the stainless screen with
alcohol wipes, or with a small amount of
denatured alcohol on a soft cloth.
d. Make sure that all components are completely
dry before reassembly.
• Never attempt to disassemble the lower half of the
microphone – it cannot be opened.
• Avoid extreme heat and condensing humidity.
• Rough handling may damage the microphone
even if no visible marks are left.
• When not in use keep the SR314 in its protective
fabric bag.
